I read somewhere here about using Sea Foam. I bought a can of Sea Foam but, have not used it because I am scare of not using it correctly. Can some of you guys instruct me on how to use it properly? I know that I should pour about 5oz on the tank, 5oz on the brake booster's vacuum line and 5oz in the motor but, don't know how long will the car smoke and if I should run it like that or just stay at one place till it stops smoking. Please provide pointers they will be greatly appreciated.
